Shijiazhuang Chenxing's vermiculite fireproof boards are manufactured using premium expanded vermiculite and fire-resistant adhesives through a series of processing steps. They feature fire resistance, thermal insulation, lightweight construction, high strength, excellent toughness, easy installation, and freedom from harmful substances. When exposed to fire or heat, they emit no harmful gases that endanger human health, producing no smoke, toxins, or odors. These boards are classified as Class A fireproof panels. Material smoke toxicity rating: ZA1. The primary component of vermiculite fireproof boards is vermiculite, containing no asbestos. They find extensive application in high-rise frame structures, communication ducts, fireplaces, ovens, high-speed rail systems, kilns, fire door cores, aluminum plants, steel mills, and related industries.
Vermiculite fireproof boards are natural, eco-friendly fire-resistant materials that have been widely used since the last century in Australia, the United States, Europe, and other countries as core fillers for fire doors—specifically, vermiculite fire door cores. Taking vermiculite fireproof boards as fire door core panels as an example, they demonstrate distinct advantages over other fireproof materials. First, it is lightweight, flame-retardant, heat-insulating, soundproof, and environmentally friendly, with all performance metrics surpassing other fillers. For fire doors of identical specifications and fire ratings, vermiculite fire doors weigh only half as much as their traditional counterparts. The reduced weight lowers the load on hinges, minimizing potential damage during use, extending the door's lifespan, and saving maintenance costs. Second, they are easy to install. Vermiculite fire doors can be trimmed to the required length during installation according to the manufacturer's design specifications, facilitating the installation process. Third, they offer cost savings. Using vermiculite fire boards as door cores eliminates many traditional manufacturing processes, reduces material storage space, and saves costs in labor, workflow, and facility space. Finally, vermiculite fireproof boards offer high fire resistance ratings. Fire doors manufactured with our company's vermiculite fireproof boards as cores achieve maximum fire resistance ratings exceeding 3 hours.
Given the outstanding properties of our vermiculite fireproof boards, we seek to establish partnerships with relevant enterprises. We offer customized production of vermiculite fireproof boards in various dimensions, thicknesses, densities, and shapes. We provide SGS third-party authoritative test reports verifying physical properties, Class A1 fire resistance, Class ZA2 toxicity, absence of heavy metals, asbestos, and formaldehyde.
